The Iranian star of Oscarinfo-icon-nominated film "The Salesman" said Thursday she would boycott the awards in protest at President Donald Trumpinfo-icon's "racist" ban on Musliminfo-icon immigrants.

"Trump's visa ban for Iranians is racist. Whether this will include a cultural event or not, I won't attend the #AcademyAwards 2017 in protest," tweeted Taraneh Alidoosti, the film's 33-year-old lead actress.

Trump is reportedly poised to stop visas for travellers from seven Muslim countries, including Iraninfo-icon, for 30 days.

He told ABC News on Wednesday that his plan was not a "Muslim ban", but targeted countries that "have tremendous terror."

"The Salesman", directed by acclaimed Iranian filmmaker Asghar Farhadi is nominated for best foreign language film at the Academy Awards, which take place next month.

Farhadi won an Oscar in 2012 for his film "A Separation".

Visa applications from Iraqinfo-icon, Syriainfo-icon, Iran, Sudaninfo-icon, Libyainfo-icon, Somaliainfo-icon and Yemeninfo-icon are all expected to be stopped for a month under a draft executive order published in the Washington Post and New York Times.

The draft order also seeks to suspend the USinfo-icon refugee programme for four months as officials draw up a list of low risk countries.
